Here's an alternative to rewinding AC coils for operation on DC circuits. Want to skip the time and expense of rewinding AC coils so they can operate on DC? Or are you won dering if it's even possible ...

When energy-efficiency costs come into play, more designers are opting for the electronically commutated motor rather than familiar AC and DC versions. For motor applications, engineers have several ...

In low-cost, high-speed motor applications, especially those inside the home, the universal motor dominates. They are as ubiquitous as the countertop blenders and the power tools they inhabit. But not ...

When picking a switch to use in electrical design, many people believe they can use any switch, provided its current rating is more than the maximum load in the circuit. This, of course, isn’t true.

As the story goes, the rock band AC/DC took its name from a label on an old sewing machine in the Young brothers’ home. It must have meant that the machine could run on either alternating-current or ...

Alternating current circuits improve the versatility and usefulness of electric power systems. In the late 1800s, Nikola Tesla demonstrated phenomena with alternating current (AC) electricity that ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

When choosing a switch to use in an electrical design project, there is a perception that it is possible to use any switch, provided its current rating is greater than the maximum load in the circuit.

The demand for smaller, lighter, and more efficient AC/DC USB power delivery (PD) chargers is always a challenge for power-supply design engineers. Below 100 W, the quasi-resonant flyback is still the ...

You can't live without your smart phone charger. I understand that. However, the charger needs a DC supply. DC stands for Direct Current (this means that you can't say "DC Current" - that would be ...
